The Asian Waterbird Census (AWC), conducted each year in January, is a waterbird and wetland monitoring programme initiated in 1987 within the framework of the International Waterbird Census. This report summarises the results of the AWC from 1987 to 2007, comprising counts at 6,705 sites in 27 countries. A total of 1,387 sites met at least one of two criteria of internationally important sites according to the Ramsar Convention. Of these, 312 sites were reported to support more than 20,000 waterbirds, and 1,382 sites recorded more than 1 percent of the biogeographic population of at least one species of waterbird. In the most recent five years (from 2003-2007), a total of 2,963 sites were counted and 673 were identified as internationally important sites. A total of 671 sites recorded more than 1 percent of the biogeographic population of at least one species of waterbird, and 137 supported more than 20,000 waterbirds. Totals of 349 waterbird species and 74 wetland-dependent species were recorded during this period. Brief status accounts, accompanied by 328 maps, are presented for 396 species, including 52 Globally Threatened species and 24 Near Threatened species. Preliminary trend analyses using the statistical package TRIM suggest that four of the eight most numerous dabbling duck species in East Asia are in decline.
